2 Claims. (Cl. 164-114) My invention relates to card punching or perforating mechanism and, more particularly, to improvements in punching machines of the type of the well known Powers duplicating punch of commerce.

Duplicating machines, as now constructed, while highly efiicient for the purposes for which they are designed, are all limited as regards range of operations and, furthermore, are susceptible of improvement as regards control of the operations of which they are capable.

With the foregoing in mind, the principal object of my invention, generally stated, is to equip a machine of the above designated type for a wider range of operations, as compared with duplicating control of all operations which the machine is capable of performing.

Specifically, the particular object of my invention is to provide an efiicient, simplified machine, operative under the control, primarily, of a master, or pattern card, to automatically punch in a tabulating card data representing perforations of the master card, and adapted for variable operation to duplicate the master card perforations, enter in whole, or in selected part, on either one, or a series, of tabulating cards, and either in the master card, or in different locations, as desired.

Another object is to provide for punching in the tabulating card or cards, other, or later data, representing perforations not punched in the master card controlling the first punching operation.

Another object is to provide a machine operative to punch, under the control of a master card, or a series thereof, a plurality of sets, or series, of tabulating cards of selected numbers in each set, or series, and means for automatically stopping the machine when the punching of each set or series has been completed.

My invention furthermore comprises a dupli-' cating punch including a field of sensing pins operative under control of a master card to set punch setting gags of a corresponding gag field, together with means for disabling selected sensing pins to render them ineffective as regards setting corresponding gags, and means for retaining a selected set-up of gags for repeat operations of the punches set by the latter.

Still other objects of my invention are to provide for automatically disabling the entire field of sensing pins when a record card is not in controlling position, retaining a selected set-up of punch gags under such conditions, providing in conjunction with master and tabulating card feed receptacles, respectively, mechanism for automatically stopping the machine when the supply of cards is exhausted from either of said receptacles, together with meansfor disabling at will the stopping means, associated with the master card feeding receptacle, and equipping the machine for retaining, under the control of a single key, a gag set-up extending throughout the entire field of punch setting gags.

Still another object is to provide manipulative means for disabling complementary sensing pins and punch gags at will.

Other objects, together with the structural details of the invention, will be apparent when the following description and claims are read in conjunction with the accompanying drawings, in which:

For the purpose of description the machine of my invention may be considered as comprising three main units, to wit, a head or sensing unit l0, an intermediate or translator unit H, and a base or punching unit l2.

The head or sensing unit Referring now to Figs. 1, 2, 4 to 8, 22 and 24, the head or sensing component comprises a sensing box, or frame 58, a field of sensing pins l3 mounted in said box in columnar rows for independent vertical movement and normally projecting below said box, pin tensioning springs I I8 interposed between the top of the box and enlargements H I on said pins, respectively, to yieldingly hold said pins in normal depressed position, and a series of pin locking slides 14, one for each row of pins, endwise movable in opposite directions to locking and unlocking positions, respectively. Leaf springs 69 secured to said box 58 and engaging notches H3 in the slides 14, urge the latter toward locking position. The slides H are provided with slots l l 4 and V-shaped noses I I5 therein and the pins IS with looking studs H6 the arrangement of these parts being such that the pins [3 may be locked, by cooperation of said studs and noses, in either elevated or depressed position,

relative to the sensing box 58. The noses H5 are shaped as described to reduce frictional resistance between the same and the studs H6 for obvious reasons. In this connection, the leaf springs 69 are stronger than the combined springs H8 of their related slides H to prevent movement of said slides by tensioned pins I3.

The above described sensing pins and locking slides are substantially the same as those disclosed in my co-pending application S. N. 538,429, filed May 19, 1931, to which attention is invited.

The sensing box, or frame, 58 is mounted, as by sleeves H1 (Fig. 4) and guide rods H8, for vertical reciprocation between the upper ends of side frame members of a supporting structure com.-

prising in the present invention legs 30 (Figs. 1-

and 24) a base plate 3! and pairs of lower, intermediate and upper sections 32, 35 and 36 (Figs. 4 and 24) respectively, forming the said frame members.

In thev normal elevated position of the sensing box 58 the locking slides I 4 are held in retracted unlocking position as follows:

Suitably mounted on the rear side of said box, is a rock shaft H having fast thereon arms 18 connected by a rod 12 (Figs. 6 and 8) to form a bail engaging said slides and retracting them to unlocking position. The said bail is held in a slide retracting position by means of arms 13 fast on the shaft TI and stationary cams 14 and I4 engaged by said arms. Springs H9 connected to arms 13 and to the box 58 urge said ball toward a slide releasing position. In the retracted position of the slides l4 the pins l3 are freely movable, the studsl l6 playing in the slots H4.

Figs. 19 and 20 show means for manually disabling individual interponents 20. A bar I18 of angular cross section is mounted by suitable shoulder screws I12 disposed in slanting slots IBI below interponents 20, springs H5 at each end of the bar retain the bar in a normal elevated position, shown by solid lines in Fig. 19. In this position, toes I63 engage the upper surfaceof I10 which prevents further rotation of said interponents. When desired, bar I18 may be pressed downward by the fingers permitting the turning of interponents 28 to inoperative position.

Suitablymounted at opposite sides of the box 58 are master card supply and storage receptacles 31 and 38, respectively. A master card is fed from the supply-receptacle 31 into a sensing chamber l9, (Figs. 2, 4 and 19) formed beneath the box 58 by perforated plates I20 and III in which chamber it is temporarily located by a card stop 66 so that any or all of said pins B can pass through perforations in said card. Subsequently, the master card is ejected from said chamber l9 into the storage receptacle 38. The mechanism for reciprocating the box 58, and feeding and ejecting the card will presently be described.

While the sensing box 58 is descending, the pins I 3 search for perforations in the master card. The pins, which do not find perforations are restrained from further movement'-: -,by the card. After those pins, which have foundg merforations have passedla prqiletermlned distance below the card, the arms'flfi ride off cams 16 and 14 thereby pefinitting the rod 12 to move to slide releasing position, under the urge of the spring H9, and

the slides to move to unlocking position under the action of the springs 69. At this time, pins l3 which have not found perforations in the master card have their locking studs H6 elevated above the noses H5 and are locked thereby in elevated position, whereas the studs of the pins which have found perforations are located beneath said noses and their pins are locked thereby in normal depressed position. Continued downward movement of the sensing box 53 will cause these pins ll which have been locked in normal depressed position to engage and depress related interponents I! of a field of the latter suitably mounted in the head or sensing component "I for depression against tensioning springs I 22.

The interponents l are operatively related to translator rods "5 of the intermediate or translator component II to set punch gags I! for a field of punches-arranged in the punching unit l2, in correspondence with the arrangement of the sensing pins l3.

In the event that there is no master card in the sensing chamber l9 it is essential that the locking slides ll be disabled against movement to locking position, otherwise all of the sensing pins l3 would be locked in depressed position, and all of the punch gags I? set thereby. To obviate th contingency, means for disabling the locking slides II are provided as follows: A pin 61 (Fig. 6) is mounted on the box 58, as by the bracket- 6|, to be engaged by an edge of a card located in the sensing chamber 19 and for elevation by said card. A tensioned lever 63 is pivoted, as at I23, on the box 58, to block movement of one of the arms 10, and thereby lock the slide retracting ball against movement to slide releasing position. When there is no card in the chamber l9, said lever 68 is in blocking position. The pin 61 is operatively connected to said lever to move the latter to ineffective position when said pin is elevated (by the presence of a card in said chamber.

The relative strength of the interponent tensioning spring I22 and the pin tensioning springs H0 is such that the former overcome the latter so that none of the interponents I! are depressed by the pins 13 when the locking slides H are disabled.

Associated with the locking slides I4 (Figs. 6'

and 18) are manually manipulative devices for disabling a selected columnar row or rows of. sensing pins 13, and comprising a series of sliding keys 40, one for each locking slide ll, suitably mounted on the box 58 for cooperation with notches I25 in the slides H to lock the latter in retracted position. The sliding keys 4. are for use when it is desired to prevent the repetition oi data in a certain row or rows of the master card being sensed. Since, as has. been explained, the pins 13 are freely movable in the retracted locking position of the slides II, when the latter are locked by said keys 40, the related pins I: which find perforations in a master card are ineffective relative to the interponents l5, and, hence to the punch gags I I also.

The master card which controls the setting of the gags I1 may be held in the sensing chamber I! for a determinate plurality of reciprocations of the sensing mechanism; so that the gags 11 will be set and reset for a corresponding plurality of cycles, thus eilecting the punching of a' corresponding number of cards which may be replicas of he card sensed by the pins l3. Normally the locking slides 48 are released at the end of each operation by a reciprocation of a universal retract bar operating on the cam portions 20 of the retract interponents 20. One or more of the retracting interponents .20 may be turned out of tn path of the universal retract bar 34 by a manual operation as is diagrammatically indicated in Fig- v ures 3, 19 and 24 so that some, and only some, of the locking slides It will be released by the said corresponding held (or fields) in the master control card are blank. It will also be understood that the translator interpreters l6 of the intermediate component may be offset or transposed in various ways as is well known in the art of multiple translators, so that, for example, entire fields of the master card may be transposed. It may be desirable" to transpose the perforations which occur in an upper ninety column field to a lower ninety column field when duplicating cards such as those which may have been punched by the device of my co-pending application, Serial No. 537,831, filed May 16, 1931. Itmay be desirable to transpose perforations representing debits and credits along with the corresponding control holes of cards, such as those illustrated in the co-pending application of Wegener, Serial No. 504,336, filed December 23, 1930. It is obvious that a partially perforated master card may be fed into the sensing chamber, and certain of the gags I! set; then the corresponding retractor interponents 20 disabled and thereafter a second master card may be fed into the sensing chamber to set other gags l1, and in this way reproduce data which has been perforated on a plurality of master cards.

A predetermined number counter designated generally at 2| (Figs. 1, 14 and 24) may be set to a predetermined indication and the machine will automatically operate to perforate replicas oft the card in the sensing chamber of the head, until the pre-set number has been reached.

The machine is started by depressing a trip key 22 (Figs. 1, 12 and 24). A depression of this key releases the main driving clutch and the machine will continue to operate until stopped by again depressing the start key 22, or by an equivalent automatic operation controlled by the usual presence of card detecting pinsof the card magazines, or by the predetermined numbering device 2i. It may sometimes be desirable to consecutively number the cards which are being perforated. This may be effected by depressing the numbering key 23 (Figs. 1, 10 and 24) It is sometimes desirable to set the gags ll under control of a master card, then hold the gags in depressed position by disabling the universal retract bar when it is desired to have many hundreds or many thousands of cards having identical characteristics. This may be done by depressing the retract control key 24, and shifting the "presence of card" sensing lever 25 I (Figs. 1, 9, 11, and 12). The lever 25 disables the card presence detecting pin of the master card magazine.

The multiple translator is an interchangeable unit as in the familiar Powers tabulating machines, and special provision is made .for readily interchanging differing translators, as will be described in greater detail hereinafter Framework For purposes of illustration the machine has been shown as sup' ported by a plurality of legs lll attached to a main base plate or table ll (Figs. 1, 3, 5 and 24) which supports the entire machine. The mechanism of the base'member ofthe system is sup-
